I woke up this morning and there was a wet spot right next to where one of my cats was sleeping. It was clear, I think. It was definitely not urine and I don't think it smelled like poop, it was kinda sour smelling. Do you think he was drooling? I don't know if this is weird or not for a cat to drool, this is the first I've seen a wet spot like this before. If it isn't drool what else could it be?

Gatsby was a terrible drooler. A happy drooler, that is when happy expect drool. It seemed to get worse when he got older. The smelly drool could have something to do with teeth problems. Gatsby was too old to have teeth removed but his drool did stink towards the end of his life.
